The title pretty much says it all. I'm looking to build a big honking fileserver, and I'm going to need at least 4 SATA ports. I've seen some vague references to Jmicron support on the P5W DH Deluxe (to enable the second set of four SATA ports) but nothing conclusive, and nothing at all in regards to speed and/or stability with the Jmicron driver.

I've pretty much settled on the P5W DH Deluxe and the only thing preventing me from ordering is confirmation on the number of SATA ports that are actually usable. Failing this, are there any other stable motherboards that support more than four SATA devices? And failing this, are there any PCIe SATA boards that are supported and don't cost an arm and a leg?

Many thanks in advance!

The jmicron controller on the P5W dh works, as in it's detected and you can access the drives.

however i've had nothing but problems with it, under linux, mac os x and windows.
In OSX, sometimes the drive on the eSATA port isn't detected, sometimes the one on the internal SATA stops responding.
In Windows, i get hangs every few minutes when transferring large amounts of data (mouse pointer gets stuck and audio stutters).
In Linux, sometimes the OS loses access to the drive and i have to umount and remount the partitions.

Furthermore i've had problems when using the PATA connector where my PATA drives drop to PIO mode for no apparent reason.

Long story short, don't use the onboard jmicron controller.

I do however have a Bytecc/Jmicron PCIe SATA/PATA RAID card and it works great with all OSes except that hardware RAID isn't supported in OSX.

If you're looking for RAID, this controller seems to be supported on OSX by the manufacturer : http://canadacomputers.com/index.php?do=Sh...;cid=IO.898.149

Hello
Does it work with the ez-Raid fonction???
And is everythings works? (Sleep/reboot/Shutdown)

Last question, Why using EFI Boot-132 instead of chamelon Efi or Efi v8?

Thanks in advance
